Java - 掃描儀不要求輸入

Question

System.out.println("Please enter the amount of money you have here: ");
Scanner have = new Scanner(System.in);
System.out.println("Please enter your starting bet here: ");
Scanner rate = new Scanner(System.in);

int moneyHad = Integer.parseInt(have.next());
int moneyRate = Integer.parseInt(rate.next());
System.out.println(moneyHad + ", " + moneyRate);

有我的代碼，這是我的輸出。

Please enter the amount of money you have here: 
Please enter your starting bet here: 1
1
1, 1

正如你所看到的那樣，它會在它詢問之前打印它們，這就是為什么輸出的第1行沒有輸入。

請快點幫我！

Answer 1

• 無需創建2個掃描程序對象
• 有一個方法返回int（scanner.nextInt（）），不需要ParseInt
• 當您在創建掃描程序對象時調用scanner .nextInt（）時，輸入為紅色

嘗試這個 ：

Scanner scanner = new Scanner(System.in);

        System.out.print("Please enter the amount of money you have here: ");
        int moneyHad = scanner.nextInt();
        System.out.print("Please enter your starting bet here: ");
        int moneyRate = scanner.nextInt();


        System.out.println(moneyHad + ", " + moneyRate);

Answer 2

你只需要一個掃描儀對象並調用nexInt()方法來獲取后面的條目。
